30651858 ÷ 857 
The aim is to understand the frequency of 857 in 30651858.

Going ahead to step 1:
857 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 857

Going ahead to step 2:
If we divide 30 by 857, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 857

Moving on to step 3:
857 can be fit into 306 0 times, resulting in a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 306 and we're left with 306.
Bring next digit (5) of the dividend behind the 306 and repeat the process: 3065 / 857

Moving on to step 4:
3065 divided by 857 is 3 with a remainder of 494.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 494 after subtracting 2571 from 3065.
Take the next digit (1) from the dividend and append it to 494, then repeat: 4941 / 857

Moving on to step 5:
When dividing 4941 by 857, we get 5 with a remainder of 656.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 4285 away from 4941, we end up with 656.
Append the next digit (8) from the dividend to 656 and continue with: 6568 / 857

Advancing to step 6:
The number 857 fits into 6568 7 times, leaving a remainder of 569.
The number 7 becomes the next digit in our result. 
Result so far: 357.0
If we take 5999 away from 6568, we end up with 569.
Bring next digit (5) of the dividend behind the 569 and repeat the process: 5695 / 857

Moving on to step 7:
857 can be fit into 5695 6 times, resulting in a remainder of 553.
Use 6 as the next digit of our solution. 
Result so far: 3576.0
Subtracting 5142 from 5695 leaves us with 553.
Bring next digit (8) of the dividend behind the 553 and repeat the process: 5538 / 857

Moving on to step 8:
857 can be fit into 5538 6 times, resulting in a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 35766.0
Deduct 5142 from 5538 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 9:
If we divide 3960 by 857, we get 4 and a remainder of 532.
Use 4 as the next digit of our solution. 
Result so far: 35766.4
Subtract 3428 from 3960 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 10:
5320 divided by 857 is 6 with a remainder of 178.
Use 6 as the next digit of our solution. 
Result so far: 35766.46
If we subtract 5142 from 5320, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 11:
857 can be fit into 1780 2 times, resulting in a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 35766.462
Subtract 1714 from 1780 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
When dividing 660 by 857, we get 0 with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 35766.462
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 13:
857 can be fit into 6600 7 times, resulting in a remainder of 601.
Write down 7 as next digit of the result. 
Result so far: 35766.46207
Deduct 5999 from 6600 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 14:
When dividing 6010 by 857, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 35766.462077
If we take 5999 away from 6010, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 35766.462077 and a remainder of 1.1e-06.
